    “…Moreover, synaptic activation of TRPV1 triggers a form of long-term depression (TRPV1-LTD) mediated by the endocannabinoid anandamide in a type 1 cannabinoid receptor-independent manner. …”

    “…Importantly, CREB-DIEDML mice and CREB-Y134F mice showed enhanced memory formation, whereas CREB-VP16 mice displayed a lowered threshold of long-lasting LTP (L-LTP) induction, strongly suggesting that CREB functions as a positive regulator of memory formation and LTP. …”

    “…The amino acid sequence of mature Ltp(TP-EW) was shown to be identical to that of mature Ltp(TP-J34), whereas the amino acid sequence of mature Ltp(TP-778) was shown to differ from mature Ltp(TP-J34) in eight amino acid positions. …”

    “…We show that, whereas in young hippocampi, inhibition of glycogen phosphorolysis disrupts the late phase of LTP in the Schaffer collateral-CA1 pathway, in aged rats, blockade of glycogen phosphorylase tends to enhance it. …”

    “…Current models of metabotropic glutamate receptor mediated long-term depression (mGluR-LTD) suggest that rapid, local synthesis of key proteins is necessary for the induction and expression of LTD. …”

    “…In our previous study using stable slice cultures of the rodent hippocampus, we found long-lasting synaptic enhancement/suppression coupled with synapse formation/elimination after repeated inductions of chemical LTP/LTD, respectively. We proposed these phenomena as useful model systems for analyzing repetition-dependent memory consolidation. …”

    “…The ability of memristive devices to reproduce synapse properties such as LTP, LTD, and STDP has been already widely demonstrated, and moreover, they were used for developing artificial neuron networks (perceptrons) able to simulate the information transmission in a cell network. …”

    “…Furthermore, we demonstrate that activation of distinct steroid hormone receptors is involved in stress-mediated alterations of mLTP. Activation of mineralocorticoid receptors (MR) promotes mLTP, while glucocorticoid receptor (GR) activity impairs mLTP. …”
